This module provides tools to create, read, write, append, and list a ZIP file. Any advanced use of this module will require an understanding of the format, as defined in PKZIP Application Note.\n\nThis module does not handle multipart ZIP files. It can handle ZIP files that use the ZIP64 extensions (that is ZIP files that are more than 4 GiB in size). It supports decryption of encrypted files in ZIP archives, but it cannot create an encrypted file. Decryption is extremely slow as it is implemented in native Python rather than C.\n\n.. The following paragraph should be similar to ../includes/optional-module.rst\n\nHandling compressed archives requires optional modules such as zlib, bz2, lzma, and compression.zstd. If any of them are missing from your copy of CPython, look for documentation from your distributor (that is, whoever provided Python to you). If you are the distributor, see optional-module-requirements.\n\nThe module defines the following items\n\nThe error raised for bad ZIP files.\n\nAlias of BadZipFile, for compatibility with older Python versions.\n\nThe error raised when a ZIP file would require ZIP64 functionality but that has not been enabled.\n\nThe class for reading and writing ZIP files. See section zipfile-objects for constructor details.\n\nClass that implements a subset of the interface provided by pathlib.Path, including the full importlib.resources.abc.Traversable interface.\n\nClass for creating ZIP archives containing Python libraries.\n\nClass used to represent information about a member of an archive. Instances of this class are returned by the .getinfo and .infolist methods of ZipFile objects. Most users of the !zipfile module will not need to create these, but only use those created by this module. filename should be the full name of the archive member, and date_time should be a tuple containing six fields which describe the time of the last modification to the file; the fields are described in section zipinfo-objects.\n\nReturns True if filename is a valid ZIP file based on its magic number, otherwise returns False. filename may be a file or file-like object too.\n\nThe numeric constant for an uncompressed archive member. …\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
